lay in. Gill 11611 reates to nnnioieinents 1n slides for use in extension tables, and like articles, and its ch cts are: first, to proyide a table slide will not he materially aliected hy 1n the we. sec- 0nd, to p (wide a set of slides wi h which a bearing is nro ided the entire length the slides, and, third, tacle slides that may he a punch ress. constructic in the to pro ide set of readily made upon I attain these objects by the l and assemblage of parts shown. accrtinpanying dra 1, ing, in which l is a per. pecti e of a set of slides s an elevation of a table top with my slides in place. i 8 is a modified form of one of the movable wings of the slide. Fig. i is another form of same. Similar numerals and letters refer to similar parts throughout the several views.

In the construction of these slides I use thin sheet metal. T he center, permanent slide is made up of two pieces stamped out to form the central planes 1 l and the sets of grro cd wings a c, and the central planes are made integral, or secured together by means of called, spot welding, as indicated hy the dotted outlines at 7 7 in Fig. 1. By this re urs I am able to form two .r grooves 2. 3, rne each side, or edge of the -.=ide in rich the ribs l of the side I and 6 will slide freely. The slid (l are made of thin sheet metal for, .a secured together, as indicated in. d 3, so as to gi e the amount or strength with sale amount i metal Feed. '1 he side wall of the side slides should he a trifle longer, or, rather, wider than the walls 0 on the central or permanent slide 1 so the slides 5 and 6 may he firmly screwed to the ends of the table and still slide freely and with no friction whatever between the table top and the permanent slide.

8 8' indicates holes through the flanges or the side shdes for the passage of screws with which to secure the slides firmly to the table tops 9 9 as indicated at 10 10 in ,2, and the permanent slide, 1, 2, c is secured to the cross piece 11 on the pedestal 13, as indicated at 12, so the slides a and 6 may he drawn in opposite directions to extend top of the table, while the slide 1, 2, c 7 .inain stationary on the pedestal.

In Fig. 1 I hare shown the side slides, 5 and 6, with downwardly extending wings F) b by means of which a groove lS fOFH'IGCl for the lower wings, c c of the permanent slide, but I find the construction shown in Fig. 8, where the wings 7) b are dispensed with. an absolutely satisfactory form of construction. and in many instances much more desirable as l eine much easier to form, requiring less material, hence less weight, and, also, requiring much less exnensi dies for forming them. than is required to form he slides shown in Pi 1.

ln Fig 2 l ha e shown two center leaves, 10. in place for the purpose of showing the table extended to more plainly indicate the relatiye positions of the se eral slides, especially when the table is extended.

What I claim as new. and desire to secure by Letters Patent of the United States, is

1. A set of table slides made up of a c nter slide ha ing two pieces cl sheet metal connected face t face horizontally. with g ooyes so formed in each edge of each sheet of metal as to open toward each ther and form an outwardly opening T shaoed .e'roo e at each edge of the slide, rt ide slides each made 0t two nieces of metal secured together horizontally and ffset to form 'l' shaped t ngues that will slide freely in the grooves in. the edges of the center slice. I

2. A set of tahle slides made no of a center slide having two nieces of sheet metal connected face to face horizontally and having a groove formed in each edge of each sheet of metal to onen toward each other and form a T sha'oed groove in each edge of the center slide, outside slides formed of two sheets of metal foldel together and the surfaces secured. said tolded metal bent to form an L shaoed slide with a i shaped tongue set off from the outside surface of one of the surfaces of one Wing of the l. in position so the surface of the other Wing of the l. will extend above the surface of the center slide, the? shaped Wings on the outer slides arranged to slide freely in the grooves in the inner slide.

3. A set of table slides made up of greenter slide composed of two sheets of thin sheetrnetal, each having a square inwardly opening channel formed the whole length at each edge and arranged to register to form a T shaped outwardly opening groove in each edge of the said center slide, said two pieces spot weldedtogetherhorizontally, and two outside slides each made of thin sheet'metal folded surface to surface and bent longitudinally'to L form, one fold of said L on each outside slide offset to form a T shaped tongue arranged to slide freely in the T shaped grooves in the edges of the center slide, and the other wing of said L made to extend above the plane of the cenfreely in, the T shaped groove in the other slide.
